[Detailed description of the device]

[0001]

[Field of Industrial Application] The present invention is an individual storage unit for liquid contents such as ramen sauce, shampoo, liquid medicine, powder soup, spice powder, granules, toys, and electric appliance parts. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous individual bag separating device for cutting continuous individual bags one by one and inserting them into a container or the like.

[0002]

2. Description of the Related Art Heretofore, there has been known a separating device for separating individual packaging bags connected by connecting pieces one by one from a connecting piece portion and putting them into a container or the like.

This conventional separating device is, as shown in FIG.
A continuous individual packaging bag (1) is arranged vertically, and this individual packaging bag is
On both sides of (1), rollers (2) connecting to the sensor are arranged. The rollers (2) are attached to both sides of the individual bag (1).
Move the individual bag (1) while sandwiched between
The individual bag (1) was separated and loaded by detecting unevenness generated in (1) and the connecting piece (3) with a sensor and cutting the connecting piece (3) with the cutter (4). . Also,
The loading of the individual packaging bag (1) into the container was performed while the individual packaging bag (1) was arranged vertically in the vertical direction.

In another different conventional example, as in the invention described in Japanese Patent Laid-Open No. 54-54791, continuous individual packaging bags are arranged in the vertical direction, and both sides of this individual packaging bag are There is a belt conveyor that connects to the sensor. Then, move the individual packaging bag while sandwiching both sides of the individual packaging bag with a pair of belt conveyors, sense the individual packaging bag and the connecting piece with a sensor, and cut the connecting piece with a cutter, The packaging bag is placed in the container while it is arranged vertically vertically.

[0005]

However, according to the conventional method, the individual packaging bag is sandwiched by the rollers. Therefore, only a part of the individual packaging bag is pressed by the rollers, and the contents move in a biased manner. To do. Therefore, in the conventional method, the irregularities generated between the individual bag and the connecting piece change irregularly, and the accurate detection of the position of the connecting piece cannot be performed, so the cutter cuts other than the connecting piece and discharges the contents. However, it has the drawback that it cannot be separated into individual bags. Further, when water, oil or the like adheres to the roller, the roller has a small contact area with the continuous bag body, and therefore slips, which results in a problem that accurate position detection cannot be performed.

Further, as in the invention described in Japanese Patent Application Laid-Open No. 54-54791, a continuous individual bag held by a belt conveyer connected to the sensor from both sides is capable of accurately detecting the connecting piece. The individual bag cut from the connecting piece is placed in the container while being arranged vertically in the vertical direction. Therefore, it is not possible to specify whether the front and back of the individual bag are placed on the upper surface or the lower surface in the container. This not only makes the appearance of the product packaging unattractive, but when storing multiple individual packaging bags in a single container, for example, in instant ramen, when storing individual packaging bags of condiments, ingredients, soup, etc. If it is on the upper surface, it may be difficult to determine the contents.

Further, if the individual packaging bag falls vertically into the container and falls down as it is, it cannot be stored in the container and often projects outward from the edge of the container. In particular, if the individual packaging bag is larger than the radius of the container, the end of the individual packaging bag will be the container when the lower end of the individual packaging bag falls vertically in the middle of the container, even if it falls in any direction. It will project outward from the edge of. If this is left as it is, the lid of the container cannot be closed, and the placement of the individual packaging bag must be corrected manually or the like, which has the drawback of making workability extremely poor.

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned problems, and in the case of separating individual packaging bags continuous by a connecting piece from the connecting piece portion one by one, separate the individual packaging bag and the connecting piece. It is possible to accurately detect the unevenness that occurs due to the sensor, to reliably cut only the connecting piece, and to reliably separate the individual packaging bag without discharging the contents. Further, even if water, oil, or the like adheres to the continuous bag body, slippage in the carrying process is prevented and accurate position detection is performed.

[0009] Further, by laying the individual packaging bag horizontally inside the container, it is possible to always make any surface of the front and back sides the front side. Even if the individual bag is larger than the radius of the container and close to the inner diameter, by horizontally laying it horizontally, it is possible to store it without protruding the end part from the edge of the container and correct it manually. This eliminates the need for an accurate and well-formed individual bag and enables quick storage.

[0010]

In order to solve the above-mentioned problems, the present invention places a continuous bag body in which a plurality of individual packaging bags for storing contents are connected through a connecting piece on a surface and horizontally. A conveyor belt that moves in the direction is provided, and on the upper surface of this conveyor belt,
A slide plate that presses the individual bag via the movement distance of the individual bag is arranged horizontally, and an unevenness sensor that detects unevenness between the individual bag and the connecting piece is arranged on the upper surface of the conveyor belt. In the feeding direction of the conveyor belt, a cutter is formed to cut the connecting piece in response to the detection signal of the unevenness sensor, and on the outlet side of the conveyor belt, a jet nozzle of pressurized air that pressurizes the individual bag upward. Is formed, and continuous individual packaging bags can be separated from the connecting piece one by one and can be placed horizontally in the container.

Further, a suction pad for adsorbing the individual packaging may be formed on the delivery side of the conveyor belt, and the suction pad may be connected to the upper and lower cylinders arranged above the loading target portion.

[0012]

Since the present invention is constructed as described above,
In order to separate a continuous bag body in which a plurality of individual packaging bags are connected by connecting pieces, first, on the surface of the conveyor belt arranged in the horizontal direction,
Place the continuous bag horizontally. This transport belt has a slide plate arranged on the upper surface thereof with a moving distance between the individual bags. Then, the slide plate presses the individual bag of the continuous bag in the direction of the conveyor belt.

An unevenness sensor is arranged on the upper surface of the conveyor belt. This unevenness sensor detects unevenness between the individual bag and the connecting piece. And
In the individual packaging bag whose surface is pressed by the slide plate, the contents can be uniformly pressed and the shape can be made constant.
Therefore, the unevenness sensor can detect a clear unevenness formed by the individual packaging bag and the connecting piece.

Further, in the continuous bag body which is horizontally moved in the delivery direction by the transport belt, the connecting piece is cut by the cutter arranged in the delivery direction of the transport belt. In this cutting, the cutter is operated in response to the detection signal generated by the concave-convex sensor, the connecting piece at the tip connecting the individual bags is cut, and the individual bags can be separated.

In this case, the timing at which the concavo-convex sensor issues a detection signal may be set when the individual bag is detected or when the connecting piece is detected. In any case, it is necessary to adjust in advance so that the cutter operates when the connecting piece at the tip for connecting the individual packaging faces the cutter.

As described above, when the unevenness sensor is used to detect the unevenness of the individual packaging bag and the connecting piece, since the continuous bag is sandwiched between the conveyor belt and the slide plate, the individual packaging is performed. The surface of the bag is pressed by the slide plate to keep its shape constant.

Therefore, in the continuous bag body, the unevenness formed by the individual packaging bag and the connecting piece is clarified, the unevenness sensor does not cause a malfunction in detecting the unevenness, and the cutter accurately cuts the connecting piece, Reliable separation of individual packaging bags is possible.

Further, since the individual packaging bag cuts the connecting piece in a state where it is transported in the horizontal direction, it can be dropped in the horizontal state. Of course, when the drop distance is long, the horizontal state is changed, but if the container is installed close to the cutting position of the connecting piece, the individual packaging bag is arranged in the horizontal state in the container.

As described above, by horizontally laying the individual packaging bags in the container in the horizontal direction, it is possible to always make an arbitrary surface of the front and back sides the front side. Further, even if the size of the individual packaging is equal to or larger than the radius of the container and close to the inner diameter, by horizontally laying it horizontally, it is possible to store the end portion without protruding from the edge of the container, Since it is not necessary to manually correct the layout, it is possible to quickly and accurately store the individual packaging bags. Further, the horizontal arrangement of the individual packaging bags in the container makes it possible to use the following auxiliary means in addition to bringing the container close to the cut portion of the connecting piece.

Further, since the continuous bag is sandwiched by a conveyor belt and a slide plate in a large area and moves in a plane, slip occurs in the conveying process even if water or oil adheres to the surface. And accurate position detection is possible.

Further, if a suction pad for adsorbing the individual bag is formed on the delivery side of the conveyor belt and the suction pad is connected to the upper and lower cylinders arranged at the upper part of the charging target portion, the suction pad protrudes from the conveyor belt. The individual bag can be stably held by the suction pad, and the connecting piece can be reliably cut. Further, by operating the upper and lower cylinders, the individual bag held by the suction pad can be stably placed on the upper surface of the loading target portion such as the container, and the individual bag can be reliably loaded without popping out.

Further, if a jet nozzle of pressurized air for pressurizing the individual packaging in the direction of the suction pad is formed on the delivery side of the transportation belt, the individual packaging that projects from the transportation belt and hangs downward. Is pressed in the direction of the suction pad by the injection of pressurized air, so that the individual bag can be reliably held by the suction pad.
